The number of Australians living with allergy has doubled in nearly 20 years, according to a new report, which examines the financial and personal costs of the chronic condition. Demand for services is unprecedented, and experts warn allergy does not just impact health - it can reshape sufferers’ lives.

The number of children being diagnosed with autism is rising, putting a heavy strain on the National Disability Insurance Scheme. The government has responded, announcing a plan to divert children away from the NDIS to a new scheme called Thriving Kids. Parents and autism advocates say they were unaware of the strategy until it was made public.

Public health experts have raised concerns about the beliefs and behaviours of individuals of reproductive age on social media. In a recent study, La Trobe University researchers looked into the rise of contraceptive misinformation on TikTok.

A chikungunya outbreak in China has infected more than 7,000 people. Chikungunya causes fever and joint pain, but in some cases can be fatal. There is no vaccine or real treatment. Epidemiologist Jason Rasgon, from Penn State University, explains how the disease is transmitted, and why it seems to be spreading to new areas. The chikungunya virus is not currently endemic in Australia. There have been no locally acquired cases, though mosquitoes capable of spreading the virus are present in some areas of Queensland, and travellers can become infected with the chikungunya virus if travelling to a region of the world where chikungunya is found.

Around the world, fertility rates are dropping. The rate for each generation to replace itself is an average of 2.1 births per woman - and many countries are well below that figure. Does it matter? Surely reducing the population will make the Earth's resources go further?
